# Recall execution error: Unavailable slot type (double booking)

A recall may fail with this error when a staff member configured for double booking prevention is no longer available in the EHR (EMIS or SystmOne). This can happen if the staff member has been renamed, removed, or is no longer accessible.

### How to fix

1. Open the [Web App](http://portal.abtrace.com/) and select your organisation.
2. Navigate to **Automated Recalls**.
3. Select the affected recall.
4. Under the **Configuration tab**, review the staff member(s) configured for double booking prevention.
5. Confirm the staff member still exists in the **EHR**.
6. Remove or replace any deleted or renamed staff members.
7. **Save** the recall.

ℹ️ **Note**: After updating the recall configuration, the changes will take effect on the next scheduled recall run.
